Capacity testing
Capacity testing is critical to ensure that agencies know where their base level of capacity is regarding rescue disciplines . Some agencies set up incidents and page out crews to respond . Crews have no prior knowledge of what they may be dispatched to , and it shows the observers where the strengths and weaknesses are in the response model . This is an effective way to ensure that agencies are working at the level they are expected to and that procedures are working to affect a safe and consistent rescue across a broad range of disciplines .
Capacity testing for simulated tree incidents is highly recommended for all rescue agencies that may be tasked to respond to tree work accidents .
Trees to be used for capacity testing should include trees which :
• Are alive .
• Have had any loose or decayed branches removed ( so that staff are not impacted by dead sticks ).
• Have a relatively open canopy structure ( e . g . not densely-growing conifers with many small internal branches ).
• Have sound and safe access to the base of the tree .
• Have limited structural defects .
• Have been inspected by an arborist .
• Are realistic in terms of expected skills in relation to high points , access methods , space onsite and worker ( casualty ) injuries .
It is strongly recommended that rescue agencies considering tree rescue capacity testing seek assistance from experienced local arborists . An experienced arborist will be able to assist with selecting trees and can simulate the role of the casualty using typical arborist climbing systems and work methods . All reputable arborists have been involved with rescue training and assessment , and will be able to provide a good , realistic simulated accident .
For assistance with contacting suitable local arborists , agencies are recommended to contact either Arboriculture Australia or the New Zealand Arboricultural Association as applicable . Contact details for these two organisations are provided on the inside front cover of this manual . By working with arborists who have been nominated by an industry body , agencies reduce the risks associated with obsolete equipment or techniques , or the impact of personal agendas , that can be encountered when working with self-described experts .
